Application filed N oven'iber 28, 1908. Serial No. 464,952.

to rims for holding clencher tires, which arecapable of being quickly a )plied to and de' tached from the wheels'o' automobiles and auto trucks, without requiring the removal of the tires from the rims.

The object of the invention is to provide a rim, to which the ordinary clencher tube or tire may be attached, and the two parts carried by a car, the same as extra tires are now carried, and capable of being quickly applied to or removed from a wheel, in case any of the tires give out, as. by puncturing, blowing up, or from any other cause.

' A. further object is to provide a vehicle wheel of peculiar, yet simple construction, comprising few parts, which is arranged to receive and operatively hold the detachable rim. And a further object is to provide .simple means for expanding, contracting and securing the. detachable rim to a wheel without disturbing the tire.

The invention consists principally of. a wheel, such as is commonly employed for automobiles and like vehicles, having a hub, spokes, and wooden folly, the telly having a section cut away to form a gap at one side of the wheel.

The invention further consists of a metallie hoop or band rigidly secured to the fellyyso as to provide a strong and serviceable wheel; the hoop having a shallow groove extending around the periphery of the wheel, and also having an inwardly formed portion which fits and fills the gap.

'in the telly, and which comprises an out-' j wardly facing pocket or stirrup.

The invention further consists oi? a detachable clencher-riin, adapted to receive. and hold the outer tube or shoe of a pneumatic tire, in which the inner tube is in cased. The clencher-rim being cross-c11t at a point corresponding to the center of the pocket in the hoop, the opposite ends of the rimbein provided with like inwardlyprojecting lugs, which are disposed in the pocket, and the rim having-a tongue formed of cuttin the rim is to permit the same to around its inner circumference adapted to fit in the groove of the hoop. The object 69 be eizpan ed and contracted for the purpose of applying the rim with a tire attached to it and securing it in the peripheral groove of the wheel hoop, as well as for removing the rim from the groove after a tire has given out, it being a particular object of the present invention to permit the applying of the tire to the rim when the latter is de-' tached from the wheel, and in this manner to provide an extra tire and rim combined to be carried on the automobile. Andthe invention further consists of simple means,

preferably comprising a right and left threaded screw operatively connected to the lugs of the rim, by means of which the ends of the rim may be spaced'apart or brought together for the purpose of applying the tire and rim to, or removing thesaid parts from, a wh'eel.

Other features and parts of the invention will be understood from the detail description which follows, and by reference to the accompanying drawings which form a part of'thls specification, and in which.-

. Figure 1 is a 'front side view of an auto wheel having-my detachable rim applied, showing the rim contracted to hold the tire in place. F ig. 2 is a similar view, showing the rim and tire expanded, as when-just applied, or as when ready to be detached from the wheel. Fig. 3 is an enlarged detail view of a portion of a wheel, with the rubber tire removed, showing the clencher-ri1n contracted, as illustrated in Fig. 1. Fig. & is a similar view, partlv' in section, showin the clencher-rini expanded by means 0t the rightand left threaded bolt. Fig. 5 is a cross section, on line 5'5 of Fig. 3, showing the groove in the wheel hoop; ing .the corresponding tongue of" the clenchcrrim fitted in'the groove. Fig. 6

Similar characters of reference designate 119 also showv hub 2, a'series of spokes '3, and a felly l, the

I parts maybe constructed-and. arranged like i folly 4 has a portion. cut away between two stirrup 7 .is provided to form a pocket or rim-11' preferably made of spring metal, ar-

3 which comprises a part of thewell-known pneumatic tires; the shoe being held in'place "circumference of the rim 1s formed-into an integral tongue or angular rib 14, which corresponds to and isintended to snugly fit into theannular groove 9.

near its opposite ends, with integral inwardly projecting lugs 17 and 19, each lug being 'erforated and ta ped, one with right, so

corresponding parts throughout the several .tion of the felly,thus' making the wheel at r 1 which. is employed for expanding and contracting the rim, as shown inFlgs. 1, 2, 3

made to the full length of pocket 8, to prevent creeping or shifting of the rim after fit-has been applied to a wheel. Bolt 20 is. fprovided centrally with a nut-like portion "."21, preferably made hexagonal to receive a wrench, by means of which the bolt may be operated to. eitherlcontract or expand the views.

In the drawing: my wheel comprises a latter preferably midefof woi'fi'lfbiftinay be made of other material, and all of these wheels commonly-employed for automobiles and similar vehicles. In order to carry outthe objects of the present" invention, the

of the spokes, as indicated in Figs. 1, 2-, 3 and 4; for the purpose of forming a clear gap or opening. The wheel is next fitted with a hoop (5, which is preferably made of iron or steel, having aninwa'rdly-bent or depressed portion .7, which is. fitted tightly in gap 5 of the folly. Hoop 6 is preferably shrunk on to the telly, the same as wagon tires are usually applied,-so as to make the arts'firmand unyielding After ho'op 6 lias been secured to the folly, the bent portion 7 takes the place of the cut-away-porthis point as strong as at any other. The

recess 8 extending. through the-wheel, the

he peripheral edge of hoop 6 is formed into a shallow groove 9, which. lies between Th'e detachable rim consists of a clencherranged for holding an outer tube-or'shoe 12,

y the inturned hook-flan cs 13. The inner im 11 is also cut or Severed'ata convenient oint in the circle, as at 15 (see Figs. 1 and ),for the purpose of renderin the rim expa'nsible and contractible. im 11-- is preferably provided and-t e other'with le t hand threads, to receive a correspondingly threaded. bolt 20,

and 4., The bolt or screw 20 is preferably 2d represents a fiat iece of metal riveted to one end, and over aps. theopposite end ee'aooa shown) from'blowing out when the rim is expanded, as shown in Figs. 2 and l.

23 represents a tube for inflating the tire,

side of the-wheel from the pocket 8, and passes through a hole (not shown) in the rim l1, and it also passes through suitable .openings in the felly and hoop.

.1 In practice, the rim should be removed from the wheel, the-tire should be applied to the rim while the latter is contracted or closed up, and then the rim should be expandedready to apply to the wheel. The tire may be inflated ready for use, either before or after the rim has been set in place on the wheel, but. it is preferred to inflate the tire before the rim is applied, so that the power generated by the mfiation of the tire together with the spring tension of the rim, may aid the screw in closing up-the rim.

Fig, 1 illustrates a complete wheel equipped with pneumatic tire, and having my expansible clencher-rim applied. In this view, the rim is shown contracted by means of screw 20, and tongue 14: of the rim is tightly embedded in groove 9, which is the service position of the parts.

In Fig. 2, the rim iris-shown expanded away from the hoo 6 at the top ofthe wheel by the operation 0 the screw 20 in the opposite direction.

Figs. 2 and :4, a clearance occurs at the upper side of the wheel, between the rim and flanges 10 of the hoop, and at such time the rim may be swung outwardly awa from thebody or tonneau of the car, as il ustrated in Fig. 7.

over the face of the wheel, in a manner to allow the filling tube 23 to be withdrawn from the hoop and felly without injury. a

To apply the detachable rim, with the tire attached, to a wheel, the filling tube should first be inserted in the openings in the hoop and'felly at the bottom of the wheel, and then the upper portion of the rim may be swung inwardly toward the vehicle until tongue 14 registers with groove 9. The rim should then be held in the last position until screw 20 is rotated in the direction to close the rim are brought together, as shown in Figs. 1 and 3, tongue 14 will be seated in groove 9, and the rim and tire will also be tightly clamped to the wheel ready for service, and'they will be held in such position until the screw is operated in the reverse direction j It will be seen from the foregoing description when read in connection with the drawings, that the present invention comprises an extremely simple, strong and practical device of the class, the essential featuresof which consists ofa wheel having the gap 5 'df-therim, prevent the inner tube (not formed in the telly; the metallic hoop 6 Wlll 0 ll ispreterablydisposed at the opposite When the rim is expanded as shown in The rim should then be forced downward up the gap in the rim. When the ends oi" 7 disposed in the gapof the felly, and also having the'peripheral groove 9 to receive the one-part expansibl'e clencher-rim 11; the said rim adapted to receive and opera tively hold the clencher tirevlfl, which ma be applied to the rim and also infiate( while the latter is separated from the wheel..-

Having thus described'my invention whatll claim as new and desire to secure by Leti said inwardly depressed portion of the hoop and longitudinal y thereof, and a screw dis-- ters Patent, is- I In a wheel, the combination of a fellyhaving opposed square ends entirel separated by an intervemn s ace which orms a gap extendin radial y t roughout the thickness of the fefiy, a hoop surrounding and secured on the felly and havin an, inwardly depressed portion dispose longitudinall in said ga and extendln radial y'throug out the thic ness'of the fel y and also having the ends of said inwardly depressed portion arranged at right angles to the felly and abutting against the similarly arran ed or square felly ends throughout the thic ness of the telly, whereby said inwardly depressed por-- tionvirtually forms a segment of the felly, a split rim providedwith means for holding it against lateral movement on the hoop and also provided with means for engaging a" tire, oppositely-threaded lugs fixed to the end portions of the rim and disposed and movable toward and from each other in.the

posed longitudinally in said depressed portion and havin 0 positely-threaded por- "tions engaging t e t ireaded lugs of the rim.

In testimony whereof I aflix my signature in presence of two witnesses.
